Try this

$text = file_get_contents("replace.txt"); $terms = explode("\n", $text); $string = "Hello World"; $string = str_replace($terms, '', $string); echo($string);

I edited this so replace.txt is the terms that are removed

Although the question isn't clearly stated, I suppose it's essentially this: You have a file with text (i.e. words separated by spaces) and you want to delete all words that occur in the list.

Assume $text contains the text to process, and $terms the lines like you posted above. Turn both into an array:

 $text = explode(' ', $text);
 $terms = explode("\n", $terms);
 $text = array_diff($text, $terms);
 $text = implode(' ', $text);

Of course you may need extra processing to get rid of punctuation and other stuff, but array_diff is essentially what does the job.
